The facility fitting auxiliary component 100 is arranged in an embedding hole of a ceiling plate. The fitted facilities 200 comprise a fitted facility body 210 and a fitting plate spring 220 fixed to the fitted facility body 210. The fitted facility body 210 is, for example, a down light. The fitting plate spring 220 has a slit 221 formed. The facility fitting auxiliary component 100 has a lock piece 130. When the fitted facilities 200 are normally fitted to the facility fitting auxiliary component 100, a tip of a lock claw 133 of the lock piece 130 is slightly fitted in the slit 221 of the fitting plate spring 220. If the fitted facilities 200 are to fall, the lock claw 133 of the lock piece 130 is caught by a slit end part 222 of the slit 221 to prevent the fitted facilities 200 from falling. |
